    (The Kiangsu Affiliated Academy of the Chinese,Academy of Agricultural Sciences)Hybrid vigour in cotton has been reported by a number of workers.Most of them dealtwith interspecific hybrids.They were mostly marked with an increase in plant growth,especially in the F_1 crosses of American Upland × Sea-island and American Upland × Egyptiancotton.In order to study the possibility of producing an extra long fibre cotton in the Yang-tze basin and the Hwangho Plain by making use of hybrid vigour,the following problemswere investigated at Nanking,Kiangsu during 1959-1962.(1)Combining ability between different interspecific crosses with special reference toyield,earliness and fibre qualities.(2)Morphological and physiological characters of economic importance in F_1 hybrids.(3)Performance of promising hybrids in field production.(4)Method of producing hybrid seeds with cheaper cost and less labour.Fifty-nine combinations were studied from 1960 to 1962,among which Pong-zai No.1(Upland cotton)×L.S.4923(Sea-island)was the best in yield and earliness.The averageyield of this F_1 hybrid in three years with 178 kg.of seed cotton or 53.7 kg.of lint cotton permow.As compared with the parents it was 94.35% of seed cotton or 82.2% of lint cotton ofthe yield of Delta-upland cotton and 187.17% of seed cotton or 172.74% of lint cotton of theyield of Sea-island L.S.4923.The fibre quality of F_1 hybrids approached Sea-island parent with a mean fibre length of40 m.m.,mean fibre fineness of 7000 meters per gram wt.,and single fibre strength of 4.5g.The methods and procedures for producing commercial hybrid cotton seed were as follows:(1)Hybrid F_0's seed was produced by hand emasculation and pollination which was ofvalue in areas abundant with hand-labor or adapted to transplanting for saving seeds up to4/5.(2)The female parent with recessive markers,was pollinated by hand without emascula-tion.In the thinning of the hybrid progeny all recessive plants were removed,leaving onlythe true F_1's.The recessive characters used for markers were virescent yellow foliage,redstem and hairy petiole of the seedling.The percentage of hybrid seed setting for differentupland cotton varieties ranged from 13% to 78%.Observations on heterosis in the characters of F_1 hybrids of G.hirsutum×G.barbadensewere summarized as follows:Plant Characters Comparison of bybrid with Upland and Seaisland parentsDays from planting to seedling Earlier than either parentDays from budding to flowering Intermediate nearer to earlier UplandDays from seedling to boll maturity Intermediate nearer to late Sea-island Days of bud development Intermediate nearer to earlier UplandDays of boll development Longer than Sea-islandDays from seedling to first boll maturity IntermediatePlant height Taller than either parentNumber of monopodia Less than either parent,but approaching Up landNumber of sympodia More than either parentNumber of fruiting points per plant More than either parentPosition of main stem nodes where first fruiting branch appears Lower than either parentInternode length of axis Longer than either parentInternode length of fruiting branch Longer than either parentPetiole length Longer than either parentLeaf area Larger than either parentLeaf lobe index Intermediate,approaching Sea-islandShedding percentage IntermediateDistribution of bolls in different parts of the plant Approaching Sea-island,most bolls setting at middle and upper parts of the plantWeight of seed cotton per boll IntermediateNumber of ovules per boll Approaching Sea-island in a lower numberMotes percentage More than either parentPistil length IntermediateCorolla area and index Larger than either parentSeed index Larger than either parentLint index IntermediateMaturity Intermediate,approaching late Sea-islandFibre length Longer than either parentFibre fineness Approaching Sea-islandYield in seed cotton Approaching Upland,higher than Sea-islandYield in lint cotton Lower than Upland,higher than Sea-islandProduction of dry matter More than either parentProduction of dry matter per square meter of leaf area More

    Cotton plantation in Shensi Province is mostly located in the droughty plains where,according to historical reasons,the cotton yields are low,thus the farmers are often hesitatinglyto choose this crop for their cultivation.According to meteorological analysis and water re-quirement studies,as well as to several years successive high yields obtained in the cultiva-tion trials,we are confident that the suitability of Shensi droughty plains for cotton growingis out of question.Through the analysis of our experimental data,the cotton field which gained a yield of50 kilograms per mu.requires 500—700 mm.of rainfalls through the whole growing season.In the middle part of Shensi,500—700 mm.of rainfalls is often concentrated during April toSeptember.Although the variability of rainfall frequency is common,but the yearly,rainfallbelow 400 mm is rare.Furthermore,the soil structure in Shensi is rather nice in keepingmoisture,provided that proper cultivation is to be practiced.In the droughty plain a soilwater content of 15% is recorded during March to May within the layer of 0—10 c.m.of thesoil and with even more moisture below that level whereas it makes a very advantageouscondition for cotton sowing and germination of seeds.Since 1955 to 1958,cotton cultivations in Wu-kun,Chien-shen,and Bu-chen had been de-monstrated with the yields reaching twice and thrice in comparison with the ordinary fields.Hence,the droughty plain cotton plantation has been developed considerably and a yearlyincrease of 54.4% in cultivated area and 128.1% per unit area yields had been obtained in theyears of 1958—1961,as compared with the economic restoration stage right after the libera-tion.The cotton growing in droughty plains is of great economic value to the native farmersas well as to the facility of agricultural mechanization.Owing to the fact that the availability of irrigation in Shensi is still limited in the recentfuture,it will be still an important measure to develop cotton plantation in droughty plains.

    棉花采用密植化学除草不中耕是当前棉花栽培另一种方法。它比早播、稀植、中耕多次的播种期晚30—40天,但提早拔秆15天左右,前后作物可以不套种。为了发挥群体增产作用,每亩密度为15000—20000株。早打顶,每株留3—4个果枝,主攻伏挑。前期用除草剂灭草,中、后期以密植控草,整个生育期不中耕。经我省连续5年多点试验和大面积示范证实,它可以克服我省3—4月播种时,低温多雨,烂种死苗和深秋低温多雨烂桃或不吐絮等不良气候的影响,能一播全苗,提高棉花品质;能避开前期棉蚜、地老虎和后期第四代棉铃虫的为害;还能调节棉花与小麦、油菜等春收作物及插早稻争季节、争劳力、争土地的矛盾,从而提高了土地利用率,争取粮棉、油棉双丰收。在同一品种,土、肥、水相当的条件下,棉花采用密植与化学除草不中耕相结合,除草效果达75—95%,其产量,一般比当地早播、稀植、多次中耕的增产两成左右。高的每亩产皮棉150—200斤。省工50%左右,降低成本20—30%。
